SAFETY-Razor.

Specification of Letters Patent.

Patented Nov. 2, 1915.

Application filed June 2, 1909. Serial No. 499,785.

To all whom/it may concern: v

Be it known that I, HENRY J. GAISMAN, a citizen of the United States, and resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

The object of my invention is to cause the blade in a safety razor to have longitudinal movement or reciprocation in the direction of the blade edge, by and during the movement of the razor along the face.

In carrying out my invention I provide a movable element, which may be the guard adapted to be actuated by contact of the same with the face as the razor is moved along the latter, with means operated by such element for causing reciprocation of the blade whereby to produce a sort of shearing cut.-

My invention also comprises the novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure 1 is a plan view of a safety razor embodying my invention; Fig. 2 is a cross section substantially on the plane of the line 2, 2, in Fig. 4; Fig. 3 is an inverted plan view, the handle being removed Fig. l is a side view of the razor inverted looking from the left in Fig. 3; Fig. 5 is a cross section substantially on the line 5, 5, in Fig. 3, and Fig. 6 is a detail perspective of the rocking member for reciprocating the blade.

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a suitable frame provided with a handle 2 arranged in any desired manner; At 3 is a rotative element journaled upon frame 1, which element may be the guard to co-act with blade 4, the edge 7 of the blade extending along but out of contact with said element. For this purpose I have shown the element 3 in the nature of a roller provided with'any desired number of annular projecting ribs 3, the surface of which may be milled or roughened to aid in causing element 3 to rotate when moved in contact with the face, which projecting portions 3 serve in the nature of guard in con nection with the blade edge. In the example illustrated the blade 4 is detachably held in a reciprocative carriage 5 that is mounted to slide upon frame 1. I have'shown said carriage 5 approximately in the nature of a plate upon which blade l rests, fingers 5" pro ecting from said plate adjacent the corners of the blade upon which the blade rests. Clips 6 at the ends of the blade serve to hold the same in position upon carriage 5, a latch or spring 7 supported by the car rlage and bearing against the heel of the blade serving to retain the latter in position between clips 6 and the carriage plate. 'Carriage 5 is shown provided with means, such as ways, for guiding it upon frame 1, for which purpose I have shown carriage 5 provided with rods 8, 9, that are adapted to be supported by frame 1. I have shown carriage 5 provided with ears or the like 5 receiving said rods, and frame 1 provided with ears 1 also receiving said rod, whereby said rods may be secured to the carriage to slide in holes in the ears 1, or said rods may be secured to ears 1 to permit the ears 5* of the carriage to slide on the rods, although the carriage may be otherwise suitably supported to reciprocate. The arrangement is such that during the reciprocations of the carriage the blade edge-may slide in the direction of its length in shaving position with respect to guard 3. The clips 6 are suitably supported in connection with carriage 5, and for this purpose may be attached directly to the carriage or the arms 6" of said clips may be connected by a cross bar 6 ,v said arms being swiveled upon rod 9, spring or springs 10 secured to carriage 5 bearing against cross bar 6 and thus acting to cause clips 6 to bear upon the blade. The latter may be inserted by swinging back the latch or spring 7. sliding the blade forwardly under clips 6 and then raising latch or spring 7 behind the blade.

' The means I have shown which reciproe-ate carriage 5 by and during the rotation of the guard or rotative element 3 are as foL lows: A1311 is a rocking lever or arm shown pivotally connected with frame 1, as by a pivot or the like 12 passing through a lug 13 on frame 1. and through a hole 11 in lever or arm 11. Said lever or arm has projections 11 on opposite sides of pivot 12 which extend in position to be engaged by rotating element 3 that is appropriately arranged to rock the lever 'or arm 11. For this purpose I have shown element 3 as provided with cranks or eccentric portions 3 disposed on opposite sides of the axis of said element, and on opposite sides of pivot 12, the cranks or eccentrics 3 being adapt- ,ed to engage the corresponding projections 11, the element 3being suitably cut awayv at 3 between two adjacent projections 3 opposite the cranks or eccentrics, to permit the entrance of projections 11*. Rock lever or'arm 11 is connected with carriage 5, for which purpose I have shown a projection 14 attached tosaid carriage and having a portion 14: entering a slot 11 in lever 11, whereby, as the latter is rocked, carriage 5 will be reciprocated. Any other suitable means may be provided for movably connecting lever or arm 11 with carriage 5 for causing said lever to reciprocate the carriage. 1

In using my improved safety razor, the blade is placed in position so that its cutting edge may be reciprocated along and in shaving position with reispectto the rotative guard element 3, and the razor is applied to the face in the customary manner, with the element 3 in contact with the face; then as the razor is drawn along the face said element will be rotated by contact with the face, the cranks or eccentrics 3 will thereby be revolved and by their contact with projections 11 of lever or arm 11 the latter will be rocked and thereby. the carriage 5 and blade 4 will be reciprocated, so that the blade edge reciprocates in a line substantially transverse to the direction in which the razor is drawn along the face, whereby the usual action of the blade upon the hairs will take place while at the same time the reciprocations of the blade cause the same to act upon the hairs substantially in the nature of a shearing cut, the reciprocations of the blade thus being caused'by the rotary action of the element 3.

My invention is notlimited to the details of construction and arrangements set forth as the same may be varied within the scope of the appended claims, without departing from the spirit of my invention.

Having now described my invention what I claim is 1. In a safety razor, a frame, means to support a blade, a rotative element position to the means for holding the blade as toform a guard for such blade, the said rotative element being operated through en gaging the surface being shaved, a lever, means for pivotally mounting the lever at one of its ends near the rotative element, means for swinging the lever in one direction, means for swinging the lever in an opposite direction, and means engaging the lever near its opposite end for communicating the movement of the lever to the blade holder.
